Abstract:
A sense amplifier includes an amplification module and a control module electrically connected to the amplification module. Herein, in a case of reading a data in a memory cell on a first bit line, at an offset compensation stage of the sense amplifier, the control module is arranged to configure the amplification module to include a first diode structure, a first current mirror structure, and a first inverter with an input terminal and an output terminal connected to each other. In a case of reading a data in a memory cell on a second bit line, at the offset compensation stage of the sense amplifier, the control module is arranged to configure the amplification module to include a second diode structure, a second current mirror structure, and a second inverter with an input terminal and an output terminal connected to each other.
